The pattern matches the "Aran Waves and Tree of Life Aran Cardigan" also listed, making it perfect for a coordinated set. ☆Size (flat measurement) ・Opening: Approximately 52 cm ・Height: Approximately 21 cm The opening is finished with ribbing, allowing it to stretch softly to fit various head sizes comfortably. It's sized to fully cover your ears on cold days. ☆Material ・Yarn: British Eroica (color number 125 / natural) is used. This high-quality wool yarn, the same as the cardigan, provides excellent warmth. ☆Care Instructions Pre-washed. When washing, please hand wash gently with a detergent for delicate items to prevent shape distortion. ☆Important Notes for Purchase This is a handmade item knitted by an amateur. Each piece is carefully knitted, but it is not as perfect as a mass-produced product. We hope that those who appreciate the texture of hand-knitting will consider purchasing it. Thank you for looking.
